Mastering the necessary knowledge and develop creative skills to design and construct mechanisms within machinery and equipment. Mastering some of the software programs for construction of a concrete mechanism (machinery and equipment), and analyze their work in order to eliminate deficiencies.

Successful completion of the study program the student receives the following subject-specific skills: understanding problems in the theory of mechanisms and machines; solving concrete problems by using scientific methods and use of appropriate software.

Introduction to the Theory of mechanisms, structure, mechanism, kinematic member, a kinematic pair, kinematic chain, the number of degrees of freedom of movement, basic mechanism, the formation of a complex mechanism, a group of Assur; Grashof conditions, the plane and spatial mechanisms, kinematics of mechanisms, the current center of rotation , speed kinematic pairs, kinematic angular velocity members. Acceleration of kinematic pairs, the angular acceleration of kinematic members, dynamics of mechanisms, external and inertial forces and moments in the mechanism, driving force (moment), Zhukovsky theorem, the forces (pressures) in the kinematic pairs of mechanisms of synthesis, the optimal synthesis of mechanisms in MATLAB softvare; the optimal parametric synthesis of mechanisms, the objective function, restrictions and punitive functions in the objective function; real mechanisms, friction and angles of friction in kinematic pairs.
